摘要

为了提高光电着舰引导系统的视轴跟踪精度和指向精度，研究了如何隔离舰体运动对光电经纬仪视轴的扰动。对舰载光电经纬仪进行建模，引入了各种扰动力矩。设计了超前滞后控制、线性二次高斯恢复（LQG/LTR）控制和H∞控制3种控制器来提高系统的性能和稳定性，详细研究了Kalman滤波和H∞加权矩阵的设计。在Matlab中对设计的控制方法进行仿真，并在摇摆台进行了试验验证。在时域、频域响应和稳定性能等方面对3种控制器进行的对比实验表明，LQG/LTR控制和H∞控制结果满足设计指标要求，稳定隔离度达到50 dB以上。基于提出的方法，经纬仪可以对着舰飞机进行稳定跟踪和精确轨迹测量，实现着舰引导。

Abstract

To increase line-of-sight (LOS) tracking and pointing accuracy of an Optic-Electro (O-E) landing guidance system

this work explores how to isolate the LOS tracking and pointing of a O-E theodolite from the carrier motion disturbance. A carrier-based O-E theodolite model was established with various disturbance factors introduced. Three kinds of controllers

Lead-lag

LQG/LTR( Linear Quadratic Gaussian/ Loop Transfer Recovery) and H∞ were designed to improve the stability and performance of the system. The Kalman filter and H∞ weighting matrix were investigated in detail. Then

the controllers were emulated in Matlab and verified on a swing bench. The compared experiments for the three kinds of controllers on time domain

frequency response and stability were performed. Obtained results show that both LQG/LTR and H∞ controllers can satisfy the design specifications

and their decoupling effects are as deep as 50 dB

which can ensure precise tracking and pointing performance of LOSs in O-E landing guidance systems.
